NC/ND thread-in oil funnel kit

Sure, you could do an oil change with a generic funnel. Heck, you could even do it with no funnel if you're a real daredevil. But why deal with a slow funnel that you have to hold in place or risk a mess when this funnel is an option? Our funnel threads in place of the oil cap, so it holds itself up. It also has the biggest bore possible, so it's impossible to dump oil (from a normal bottle!) in too fast. It also addresses an annoying drawback with funnels - their tendency to drip oil long-term. This funnel includes a base, so the funnel sits upright while it's being stored, with the base capturing the oil that drips down over time. Last but not least, this is 3D-printed in-house out of Onyx - a carbon fiber-infused nylon that's unaffected by engine oils (among other things).

The NC and ND Miatas use a "bayonet" style of threading that we've mostly* duplicated here. *Since we're not using an O-ring (we don't need to tightly seal the outside of the funnel), we use notches at the top of the thread. There might be a tiny bit of wobble, but not much, and it's not possible for it fall out. In order to remove it, you'll need to pull up slightly then unthread. Short version, the thread we use is an improvement (for our purposes) over the stock thread.
